Wind Loads on Triangular Shape Tall Buildings

Muftha A. Abdusemed, Ashok K. Ahuja

Present paper describes the details of the experimental study carried out on the models of tall buildings with varying cross-sectional shapes under both stand-alone condition as well as interference condition. Two cross-sectional shapes namely square and triangular are considered. Force measurements are made on the rigid models of tall buildings made of timber. The models are tested in an open circuit boundary layer wind tunnel. Twisting moment developed due to wind is measured in addition to base shear and base moment in along-wind direction as well as across-wind direction. Effect of wind incidence angle on wind loads is studied in case of isolated condition. In case of interference condition, effect of distance between object building and interfering building on wind loads is studied.
